Molecular Identification of Gambierdiscus and Fukuyoa (Dinophyceae) from Environmental Samples [PDF]

Marine Drugs, 2017
Ciguatera Fish Poisoning (CFP) is increasing across the Pacific and the distribution of the causative dinoflagellates appears to be expanding. Subtle differences in thecal plate morphology are used to distinguish dinoflagellate species, which are ...

Ciguatoxicity of Gambierdiscus and Fukuyoa species from the Caribbean and Gulf of Mexico. [PDF]

PLoS ONE, 2017
Dinoflagellate species belonging to the genera Gambierdiscus and Fukuyoa produce ciguatoxins (CTXs), potent neurotoxins that concentrate in fish causing ciguatera fish poisoning (CFP) in humans. While the structures and toxicities of ciguatoxins isolated

Toxicity and growth characteristics of epiphytic dinoflagellate Gambierdiscus silvae in Japan.

Harmful Algae, 2022
The genus Gambierdiscus is a marine benthic/epiphytic dinoflagellate that has been investigated worldwide as the causative agent of ciguatera poisoning (CP).

Alternative method to detect compounds produced by Gambierdiscus spp.

Frontiers in Marine Science, 2014
Ciguatoxins (CTXs) and CTX precursors are produced by several Gambierdiscus spp. These polyether toxins are associated to ciguatera fish poisoning (CFP). In addition to CTX, maitotoxins (MTX) and gambierol are also produced by these dinoflagellates.

Ciguatoxins and Maitotoxins in Extracts of Sixteen Gambierdiscus Isolates and One Fukuyoa Isolate from the South Pacific and Their Toxicity to Mice by Intraperitoneal and Oral Administration

Marine Drugs, 2017
Ciguatoxins (CTXs), and possibly maitotoxins (MTXs), are responsible for Ciguatera Fish Poisoning, an important health problem for consumers of reef fish (such as inhabitants of islands in the South Pacific Ocean).

Genetic diversity and distribution of the ciguatera-causing dinoflagellate Gambierdiscus spp. (Dinophyceae) in coastal areas of Japan. [PDF]

PLoS ONE, 2013
BackgroundThe marine epiphytic dinoflagellate genus Gambierdiscus produce toxins that cause ciguatera fish poisoning (CFP): one of the most significant seafood-borne illnesses associated with fish consumption worldwide.

Toxicity Characterisation of Gambierdiscus Species from the Canary Islands [PDF]

Toxins, 2020
In the last decade, several outbreaks of ciguatera fish poisoning (CFP) have been reported in the Canary Islands (central northeast Atlantic Ocean), confirming ciguatera as an emerging alimentary risk in this region. Five Gambierdiscus species, G. australes, G. excentricus, G. silvae, G. carolinianus and G.

Developing model systems for dinoflagellates in the post‐genomic era

Journal of Phycology, Volume 59, Issue 5, Page 799-808, October 2023., 2023
Abstract Dinoflagellates are a diverse group of eukaryotic microbes that are ubiquitous in aquatic environments. Largely photosynthetic, they encompass symbiotic, parasitic, and free‐living lineages with a broad spectrum of trophism. Many free‐living taxa can produce bioactive secondary metabolites such as biotoxins, some of which cause harmful algal ...

Survey of epiphytic microalgae to evaluate risk of ciguatera fish poisoning across natural and artificial reefs in North Carolina

Frontiers in Marine Science, 2023
Epiphytic microalgae are important contributors to the carbon and nutrient cycles yet are often overlooked during ecological surveys. In reef habitats, epiphytes are often found living on host organisms, including seaweeds or corals, and can influence ...

Antibiotics reduce Pocillopora coral‐associated bacteria diversity, decrease holobiont oxygen consumption and activate immune gene expression

Molecular Ecology, Volume 32, Issue 16, Page 4677-4694, August 2023., 2023
Abstract Corals are important models for understanding invertebrate host–microbe interactions; however, to fully discern mechanisms involved in these relationships, experimental approaches for manipulating coral–bacteria associations are needed. Coral‐associated bacteria affect holobiont health via nutrient cycling, metabolic exchanges and pathogen ...
